Ecommerce website design

I want to have a design for an ecommerce web site for a ceramic pottery artist to attract customers to view and purchase pottery and ceramic art works. I want the site to include a slide show and 12 galleries for various categories of pottery and ceramic art. I also want to advertise for people to sign up for pottery lessons and workshops in person at my studio, and I want to provide people the option of registering and paying online for the classes they want to take at my studio. I also want the site to have a control panel where I can update the site and add new inventory items and the related images and information and remove sold or discontinued items and related images and information myself. I also want the site to include an optional blog component that I can publish and display when I want to and can deactivate and hide when I don't have time to maintain it. I also want to associate this site with an eBay store and I want the site to be white-hat SEO optimized and to have the tools in place for me to manage and maintain white-hat SEO optimization.
